NameError: name '(Whatever)' is not defined

This error is driving me crazy.

I'm developing an App Engine Python application. These are the classes:

from google.appengine.ext import db

class Usuario(db.Model):
  user = db.UserProperty()
  nombre = db.StringProperty(required = True)
  pasaporte = db.ReferenceProperty(Pasaporte)

class Pasaporte(db.Model):
  direccion = db.StringProperty()
  telefono = db.PhoneNumberProperty()

class Sindicato(db.Model):
  nombre = db.StringProperty(required = True)
  direccion = db.StringProperty()
  telefono = db.PhoneNumberProperty()

class Sede(db.Model):
  nombre = db.StringProperty()
  direccion = db.StringProperty()
  telefono = db.PhoneNumberProperty()
  descripcion = db.StringProperty()

class Servicio(db.Model):
  nombre = db.StringProperty()
  descripcion = db.StringProperty()
  prestador = db.StringProperty()
  condiciones = db.StringListProperty()

class UsuarioServicio(db.Model):
  usuario = db.ReferenceProperty(Usuario, collection_name='servicios_collection')
  servicio = db.ReferenceProperty(Servicio, collection_name='usuario_collection')
  fechaRegistro = db.DateTimeProperty(auto_now_add=True)

I don't know why but this is the error message I get when trying to test my application in localhost:

NameError: name 'Pasaporte' is not defined

In UsuarioServicio class I'm referencing to other classes without getting any error.

If helps, I'm working in Kubuntu 10-10 on Eclipse-Pydev with Python2.7 interpreter. Anyway, if I try to launch the application from terminal through 'dev_appserver.py'command, the error is displayed anyway.

What is wrong with my code?

Pasaporte isn't declared until after it is used in Usario. Switch the order of those classes and it will be fine.
